Do Dobermans go to heaven?

Momma told me that all dogs go to a place called "Heaven" when they die. Heaven is this super duper place that's supposed to be like the best place ever, and only good humans get to go there. Bad humans go to a place that's like all fiery and horrible called Hell.

But what I don't understand is if good people go Heaven, and all dogs go to Heaven, then what about Dobermans? I can't imagine that Heaven could be that wonderful a place to be if there's a bunch of nasty and evil Dobermans there, right?
